I am trying to compile the pentaho samples on OSX from here.
Sample1.java extends AbstractReportGenerator.java.
I have exported the CLASSPATH in the console to include the pwd:
export CLASSPATH=/Users/xxx/java-dev/pentaho/:/Users/xxx/java-dev/pentaho/lib/
I have compiled AbstractReportGenerator.java successfully using javac, into the same folder as the Sample1.java file, however when I try and compile Sample1.java it always fails with 3 errors related to AbstractReportGenerator.
Any suggestion on the cause and solution ?
Folder structure:
Working Folder >
- Sample1.java
- AbstractReportGenerator.java
- AbstractReportGenerator.class
- AbstractReportGenerator$1.class
- AbstractReportGenerator$OutputType.class
- lib
- pentaho .jar files
Command:
javac -cp "lib/*" Sample1.java
Sample1.java:41: error: cannot find symbol
public class Sample1 extends AbstractReportGenerator
^
symbol: class AbstractReportGenerator
Sample1.java:61: error: cannot find symbol
final ClassLoader classloader = this.getClass().getClassLoader();
^
symbol: method getClass()
Sample1.java:132: error: package AbstractReportGenerator does not exist
new Sample1().generateReport(AbstractReportGenerator.OutputType.PDF, outputFilename);
^
Note: Sample1.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.
3 errors
Try using:
javac -cp lib/*:. Sample1.java
Thanks so much for all the suggestions, after adding a target folder, this suggestion from #Roman Vottner finally worked:
javac -cp ./lib/*:./target -d ./target AbstractReportGenerator.java Sample1.java

How to compile java package structures using javac
(6 answers)
What does a "Cannot find symbol" or "Cannot resolve symbol" error mean?
(18 answers)
Closed 2 years ago.
I have been trying to compile through CMD by creating packages manually. I tried the command javac -d . Nameinfo.java and javac -d . Returndata.java, where Nameinfo contains the calculations and Returndata contains main function, and this command worked absolutely fine. Now I made 2 different packages in my "java programmes" folder i.e packx and packy, where packx contains Nameinfo and packy contains Returndata. Now, when I compile these two, Nameinfo.java got compiled but Returndata could not read/recognize the imported Nameinfo in Returndata.java.
errors:
E:\java programmes>cd packx
E:\java programmes>cd packx
E:\java programmes\packx>javac Nameinfo.java
E:\java programmes\packx>cd..
E:\java programmes>cd packy
E:\java programmes\packy>javac Returndata.java
Returndata.java:2: error: package packx does not exist
import packx.Nameinfo;
^
Returndata.java:7: error: cannot find symbol
Nameinfo data = new Nameinfo();
^
symbol: class Nameinfo
location: class Returndata
Returndata.java:7: error: cannot find symbol
Nameinfo data = new Nameinfo();
^
symbol: class Nameinfo
location: class Returndata
3 errors
if java or javac needs, say, packx.Returndata as a type to do something, it will scour a classpath and/or sourcepath for a directory named packx, and within that, Returndata.java or Returndata.class depending on the tool and path we're talking about.
So, you're in E:\java programmes\packy, and you're compiling some code that imports packx. Therefore, javac will look in the classpath for packx/Returndata.class and in the sourcepath for packx/Returndata.java and it doesn't find what you want because E:\java programmes isn't on the source path; generally they default to . (i.e. the current directory).
Stay in the E:\java programmes folder for all this work:
E:
cd "\Java programmes"
javac packx/Nameinfo.java
javac packy/Returndata.java
Or better yet, realize that manually compiling a multipackage java application is crazy. Use maven, gradle or some other build tool that takes care of all this for you :)
I am trying to compile the xslt2-transformer extension, because I can’t find the LibreOffice extension xslt2-transformer.oxt on the web site (if anybody has it, he is welcome).
To build from source code, I proceeded like that:
$ git clone https://github.com/dtardon/xslt2-transformer.git
$ cd xslt2-transformer/
$ make
I am getting a lot of (similar) errors during build:
mkdir -p build/classes && \
javac -d build/classes -source 1.5 -target 1.5 \
-cp "external/saxon9.jar:" com/sun/star/comp/xsltfilter/Base64.java \

I think my CLASSPATH is not up-to-date. I need to add the com.sun.star package and classes.
Since I am (currently) on OSX, my LibreOffice is installed on /Applications/LibreOffice.app and I found some classes in ./Contents/Resources/java.
So I update the CLASSPATH that way:
export CLASSPATH=/Applications/LibreOffice.app/Contents/Resources/java:$CLASSPATH
But, I have the same errors. How can I fix that?
EDIT 1 put some jar in the CLASSPATH
I tried that:
$ export CLASSPATH=/Applications/LibreOffice.app/Contents//Resources/java/ridl.jar:.
I have less errors.
EDIT 2 The build succeed!
I finally added the following jar files to the CLASSPATH:
/Applications/LibreOffice.app/Contents//Resources/java/ridl.jar
/Applications/LibreOffice.app/Contents//Resources/java/jurt.jar
/Applications/LibreOffice.app/Contents//Resources/java/juh.jar
/Applications/LibreOffice.app/Contents//Resources/java/unoil.jar
And I get the extension!
Finally, to build from source code, I proceeded like that:
git clone https://github.com/dtardon/xslt2-transformer.git
cd xslt2-transformer/
export CLASSPATH=/Applications/LibreOffice.app/Contents/Resources/java/ridl.jar:\
/Applications/LibreOffice.app/Contents/Resources/java/jurt.jar:\
/Applications/LibreOffice.app/Contents/Resources/java/juh.jar:\
/Applications/LibreOffice.app/Contents/Resources/java/unoil.jar
make
The result is build/xslt2-transformer.oxt.
My project runs smoothly in Eclipse, no errors at all. I ran it through local tests (that are equal to the ones in an online mooshak contest) and all checks out. But when I sumbit it online, I get a CompileTimeError.
To try to locate the problem, I attempted to use javac in Main.java, and this happened:
javac -encoding US-ASCII Main.java
Main.java:8: error: package code does not exist
import code.*;
^
Main.java:129: error: cannot find symbol
public static void addWords(Scanner in, LibSystem system, int wordCount)
{
^
symbol: class LibSystem
location: class Main
Main.java:153: error: cannot find symbol
public static void searchWord(LibSystem system, String word) {
^
Other symbol errors follow for every reference to classes from my only package, which I fully import and the header of Main, for a total of 29 errors.
Project
src
Main.java
code (package with all my other java files)
Follow these steps :-
1.) make sure LibSystem class is in classpath.
2.)Compile java files in code folder using -d option. That will create directories with classes.
javac -d . code/*.java
3.) then compile your Main class.
javac Main.java
I have my file structure as (they are in the package assigment):
prog/
src/assignment/
bin/assignment/
lib/assignment/
The files I am compiling are in src, and are being compiled to bin. The command I type is javac -d ./bin/ -cp ./bin/:./src/ -target 1.7 ./src/assignment/*.java
I have also tried javac -d ./bin/ -cp ./bin/:./src/ -target 1.7 ./src/assignment/GoodBrain.java ./src/assignment/LameBrain.java ./src/assignment/Board.java
For some reason I cannot two class files, the error message is 'cannot find symbol' (it points to the Board class and the LameBrain class).
The error message:
javac -g -d ./bin/ -cp ./src/:. -target 1.7 src/assignment/GoodBrain.java
src/assignment/GoodBrain.java:3: error: cannot find symbol
public class GoodBrain extends LameBrain{
^
symbol: class LameBrain
src/assignment/GoodBrain.java:11: error: cannot find symbol
public double rateBoard(Board board) {
^
symbol: class Board
location: class GoodBrain
2 errors
make: *** [bin/assignment/GoodBrain.class] Error 1
It is the same error for all the commands that I type in. Please tell me if I need to provide any new information
I fixed the error, it was because I forgot to include the package statement. Very dumb mistake
I have downloaded the sample file from jocl.org and compiled it without problems (c:\javac -cp c:\jocl.jar JOCLSample.java)
When I tried to run it (c:\java -cp c:\jocl.jar JOCLSample), some errors occurred:
C:\Users\Ruoyu>java -cp C:\j.jar JOCLSample
Error: Could not find or load main class JOCLSample
How do I correct this?
If JOCLSample.class is in C:\Users\Ruoyu, change your -cp parameter to C:\j.jar;C:\Users\Ruoyu
